The Department of Public Health (DPH) Division of HIV
and STD Programs (DHSP) utilizes mapping to inform
distribution of resources for HIV and sexually
transmitted disease (STD) prevention and treatment in
Los Angeles County. Geographic Information Systems (GIS)
is a computer system designed to capture, store,
manipulate, analyze, manage, and present spatial or
geographic data. DHSP has been using this important tool
since 2004 to develop maps to identify geographic areas with higher HIV and STD burden
facilitating improved distribution of scarce resources
to the communities and people most in need. Data for the
GIS is captured from various sources including DHSP's
HIV Surveillance data, STD Surveillance data, HIV
Testing Services data, HIV Care Services Utilization
data, and the Los Angeles Coordinated HIV Needs Assessment (LACHNA).
The maps created from the captured data in GIS is used
in conjunction with other data sources to not only aid
in resource distribution, but also to evaluate the
effectiveness of HIV and STD prevention and care

DHSP Mapping Project - 2010-2014 HIV & STD
Burden by Health District
The latest mapping endeavor, 2010-2014 HIV & STD
Burden by Health District, ranks geographical areas in order of highest to lowest
HIV and STD burden throughout LAC to more efficiently
distribute resources to communities in most need.
Geographic areas (health districts) are ranked by
several important driving factors for the geographic
burden of HIV and STDs: number
of infections, number of people infected, the population
size, geographic size, and results from the hot spot
The 2010-2014 HIV & STD Burden by Health District
plays a critical role in informing and updating DHSP's
continuing efforts to reduce new HIV and STD incidents
and account for all reported cases of HIV and STDs in
the City of Long Beach, City of Pasadena, and throughout
LAC. Its primary purpose is to support geographic
prioritization of DHSP resources by
updating and building upon the GIS syndemic cluster maps
produced by DHSP in 2009. Additionally, the new mapping
strategy shares regularly collected HIV and
STD surveillance data in a way that highlights the
interrelationships between HIV, syphilis, gonorrhea and chlamydia. Rather than looking at each disease in isolation, the mapping of HIV
and STD Burden
by Health District allows for each HIV/STD to be viewed
in the context of a person's other diseases and from
several other vantage points, including:
1. Aggregated to health districts for detail on HIV and STD infected populations (i.e., health district profiles);
2. Aggregated to census tracts for LAC disease-specific maps showing the differences of disease spread relative to risk fo HIV infection or transmission (i.e., bivariate maps); and
3. Aggregated to census tracts and analyzed using hot spot analysis to map where we have unexpectedly higher numbers of incidents (i.e., HIV/STD Highly Impacted Areas maps).
By building upon the 2009 syndemic cluster mapping and
by sharing data in these various ways, DHSP and agencies
critical to reducing new HIV and STD infections will
have the information needed to create truly synergistic
prevention and treatment programs for both HIV and STDs.
